Boron Granules are made from the powdered form of the chemical element boron. With its exceptional hardness, refractory nature and ability to absorb neutrons, boron has versatile industrial applications. These granules are commonly used as an alloying agent for steel to increase hardness, as a component in pyrotechnic flares, and as a neutron absorber in nuclear reactor control rods. We offer Boron Granules in various sizes and purities to suit different manufacturing needs. With 8 variations available, our range offers customizable solutions for working with this useful material.
